Question

The sample for a study was randomly selected from a list of registered nurses (RNs) obtained from the Board of Nurse Examiners (BNE) for Texas. The study had a cultural focus, so the final sample included 100 Caucasian, 100 Hispanic, and 100 African American RNs. What type of sampling method was used in this study?

A. Convenience
B. Simple random
C. Stratified random
D. Systematic

Answer 1

The study used stratified random sampling by dividing registered nurses into subgroups based on cultural background and randomly selecting equal samples from each subgroup.

Step-by-step explanation:

The sampling method used in the study described is stratified random sampling. This procedure involves dividing the population into subgroups, or strata, based on a specific characteristic—in this case, the cultural background of registered nurses. Afterward, researchers draw random samples from each of these subgroups ensuring representation from each category, hence 100 Caucasian, 100 Hispanic, and 100 African American RNs were selected. Unlike simple random sampling, which does not consider subgroups, or convenience sampling which is not random, stratified random sampling aims to capture the population's diversity and ensure that each subgroup is adequately represented in the sample.
